The problems faced by the students in chemistry class, especially in Buffer Solutions, often caused a misunderstanding. Continuous misunderstanding can lead to a misconception. This study aimed to analyze the misconceptions in Buffer Solutions among the eleventh grade students of MA Darul Ulum Kubu Raya 2016/2017 using a Diagnostic Test instrument. Using a descriptive method, the data revealed collected by employing 10 items of multiple choice with their reasons. The study revealed that the misconceptions in Buffer Solutions occurred in all concepts. The most common misconception took place in the indicator of explaining how the base buffer solution works when it is added by a small amount of alkaline (80%). The lowest happened on the indicator of determining the mixture of compoundsof the acid buffer solution (31%). The misconception that occured in each indicator was 70.4%. The misconception was caused by the students’ associative thinking skills was 48.4%. Therefore, the factors related to misconceptions faced by the students in Buffer Solutions are the lack of understanding, the learning methods applied by the teacher, and the reference books, particularly the non-school text books.

The research was based on low learning outcome of XI IPA class student of SMAN 1 Sungai Raya in chemistry especially sub material of hybridization theory. This research aimed to determine difference in learning outcome between student taught by using index card match learning strategies with students taught without using index card match learning in the sub material of hybridization theory class XI IPA of SMAN 1 Sungai Raya. This research used Control Group Pretest-Posttest Design with the research subject was 29 control class students and 28 experiment class student XI IPA class SMAN 1 Sungai Raya. Techniques and data collection tools used learning result test, observation, and interview. The result of data analysis showed that the average value of pretest control class was 38,45 and the average value of posttest class was 52,60 while the average value of pretest experiment class was 21,25 and posttest average value is 75,13. Statistic analysis result U Mann-Whitney test showed the significance value of 0,000 that was smaller than α (0,000 < 0,05) which mean that there are differences in student learning outcome taught by using index card match learning strategy. The amount of increase in learning outcome was known from the calculations effect size value as big as 0,94 in high category as big as 82,64%. Therefore, index card match learning strategy can be applied to sub material hybridization theory to improve student learning outcome

This research was motivated by the low learning outcomes of students in chemistry subjects, especially the material of acid and base solutions. The purpose of this study was to determine the use of comics as a learning medium for acid and alkaline solution material as well as student learning outcomes before and after using comics as a learning medium in class XI SMK Negeri 7 Pontianak. The method in this study is an experiment with the form of pre-experimental research. Data collectors used measurement techniques and data collection tools namely pretest-posttest questions. Data analysis used statistical analysis techniques. Based on the results of the study it was found that there were significant differences in student learning outcomes between before and after using comics as a learning medium for material of acid and base solutions in class XI SMK Negeri 7 Pontianak. This difference is obtained from the comparison of the average pretest and posttest results of students is 25,793 and 82,379. This means that the posttest results are greater than the results of the pretest. Based on statistical analysis with ttest, it is known that the results of the comparison of the results of the pretest is greater than the ttable, which is 16.090 > 2.048 which indicates that Ho rejected and Ha accepted. The comparison value of tcount the posttest result is greater than ttable that is 59.668 > 2.048 indicates that Ho is rejected and Ha is accepted. If Ho is rejected Ha accepted means there is a significant difference between the results of the posttest and the results of the students' pretest. So it can be concluded that comics can be used as a learning medium in improving the learning outcomes of chemistry in material of acid and base solutions in class XI SMK Negeri 7 Pontianak.
